ROME – Psoriasis patients with a past history of bone or joint trauma had about 50% higher risk of later developing psoriatic arthritis than did those without a history of trauma in a longitudinal, population-based study of more than 70,000 psoriasis patients in the United Kingdom.
The relationship between trauma and later development of psoriatic arthritis could involve a deep Koebner phenomenon similar to what is observed with the Koebner phenomenon in the skin, suggested lead investigator Dr. Thorvardur Löve in an interview at the European Congress of Rheumatology.
Based on these findings, “one of the things that we are very excited about is the potential to think of strategies and test strategies that might be used in psoriasis patients once they are injured. So should we do anything different in an injured psoriasis patient, for instance, some sort of preventive treatment?” said Dr. Löve of Landspitali University Hospital in Reykjavik, Iceland.
